Caffeine is my primary neurotransmitter. I have, fortunately, weaned myself down from two airpots before noon. SWMBO told me I twitched in my sleep when I was drinking it in gallon quantities. Currently, it's 12:45CST and I've had 3 large cups since 1000.

On a happy note, I've got 220 run to my espresso machine and plumbed it into the bar. Now I don't have to settle for drip.
